I've been trying to access my MiGo Thermostat data via the API.
I've managed to get an access token and refresh token but the device list is always empty.

A few questions that I would be grateful for any answers to:
- Is there a separate auth flow for authorising the third party application per device that is required first?
- What is the difference (if any) between the https://api.migo-thermostat.com and https://api.netatmo.com endpoints?
- The migo-thermostat auth endpoint does not currently give me an access token (invalid_client), however I am able to use an access token from the netatmo endpoint on other migo-thermostat endpoints.
